The Free downloadable trial version is a fully functional version of the Ultimate ZIP Cracker. The only exception is that the passwords longer than 5 characters in length are not shown.

To prove that the passwords are actually detected the program allows you to view the beginning of each encrypted file. You can then purchase the password recovered by the downloaded trial version of Ultimate ZIP Cracker in the online store. At the end of the search after the password is found (so you know that you will actually receive your password!) you will be prompted to go to the online store
